More problematic, I simply didn't believe Hemingway's characters. I thought the protagonist fell in love because the book required it, and I never got any firm picture of who Catherine Barkley actually was. The obvious contrast for me is Wharton's Madame Olenska and Newland Archer, where you see two people falling in love out of a kind of need. I don't really believe in literary romance for romance's sake. I think love comes from actual places.
I've had this problem with other "great books." I recently re-read Invisible Man and found myself not caring much about the characters. But I still enjoyed the form of the book. I was reading something more like an allegory, than a deep character study.
Anyway, I think as writers we find a few people we love and we devour them. Hemingway is off my menu.
